This presents value semantics for a stack of constant values.
Internally it shares ownership to avoid copies. Previously
this was implemented by `cmListFileBacktrace` explicitly,
but the approach can be re-used for other kinds of stacks.
Move backtrace printing functions from `cmListFileBacktrace` over to
`cmMessenger`, their primary caller. Thread `cmMessenger` instances
through APIs needed to update other call sites.
If a path argument with no -S or -B leads to a cache directory,
use that directory as the binary directory. Otherwise, use the
binary directory from the preset.

#pragma once is a widely supported compiler pragma, even though it is
not part of the C++ standard. Many of the issues keeping #pragma once
from being standardized (distributed filesystems, build farms, hard
links, etc.) do not apply to CMake - it is easy to build CMake on a
single machine. CMake also does not install any header files which can
be consumed by other projects (though cmCPluginAPI.h has been
deliberately omitted from this conversion in case anyone is still using
it.) Finally, #pragma once has been required to build CMake since at
least August 2017 (7f29bbe6 enabled server mode unconditionally, which
had been using #pragma once since September 2016 (b13d3e0d)). The fact
that we now require C++11 filters out old compilers, and it is unlikely
that there is a compiler which supports C++11 but does not support
#pragma once.
An old workaround for `std::allocator_traits<>::value_type` lints from
IWYU on `std::vector<>` usage breaks IWYU's handling of `<memory>`.
Convert the workaround to use the same approach we already use for a
workaround of `std::__decay_and_strip<>::::__type` lints. Then update
the `<memory>` inclusions to follow the now-correct IWYU lints.
They are unused, but if someone used them they would lead to
problems since they would copy the internal raw pointers
and the destructor would cause double delete

-- Forward GHS platform variables to try_compile()
CMAKE_TRY_COMPILE_PLATFORM_VARIABLES only worked for source signature try_compile()
-- Update tests to no longer add GHS platform variables to try_compile()
-- Avoid linker error in GhsMulti/GhsMultiCompilerOptions/CMakeLists.txt by building library
Since commit v3.10.0-rc1~391^2~3 (Add directory property 'LABELS' and
CMAKE_DIRECTORY_LABELS variable, 2017-06-23) this command was
accidentally not allowed in script mode. It was dropped because
`ctest -S` mode needs to start with CMake's normal script mode and
then replace the `set_directory_properties` implementation. Restore
the normal `set_directory_properties` in script mode and then add
special logic to replace it in ctest. Also add a test case.
Fixes: #18523
